Titanium Software today announced the release of OnyX 1.9, a new version of its popular maintenance, optimization and personalization utility for Mac OS X 10.5 Leopard. According to the developer, OnyX 1.9 has been totally rewritten for Leopard. Notable changes and bug fixes include:

I dig the new icon, but I'm having trouble with the application itself. I can't get past the verifying startup volume stage without it asking me to repair the permissions. I've repaired the permissions in Disk Utility, which is still acting flaky in 10.5.1, but it hasn't done anything to help me get past that stage. It's a vicious circle!
